Kata Instructions

You should implement a supermarket checkout which:

• always accepts a string of items and gives back the total price
• discounts any offers from the total price

Use the following pricing information:

Item	Price	Offer
A	50	3 for 130
B	30	2 for 45
C	20	N/A
D	15	N/A

For example:

• 'DABA' gives 145
• 'BBBB' gives 90
